Looking for JellyBean Rom for Thrive 10.1 with AT&T 3G/4G

Late last year I downloaded a Jelly Bean rom for my Toshiba Thrive 10.1 with AT&T 3G/4G. I never got around to up dating my Thrive, now I can but I need the rom again. Is this rom still available or what rom should I install? Thanks for any help.
